Merge branch 'next-integrity' of git://git.kernel.org/pub/scm/linux/kernel/git/jmorris/linux-security
Pull integrity updates from James Morris:
"This adds support for EVM signatures based on larger digests, contains
a new audit record AUDIT_INTEGRITY_POLICY_RULE to differentiate the
IMA policy rules from the IMA-audit messages, addresses two deadlocks
due to either loading or searching for crypto algorithms, and cleans
up the audit messages"
* 'next-integrity' of git://git.kernel.org/pub/scm/linux/kernel/git/jmorris/linux-security:
EVM: fix return value check in evm_write_xattrs()
integrity: prevent deadlock during digsig verification.
evm: Allow non-SHA1 digital signatures
evm: Don't deadlock if a crypto algorithm is unavailable
integrity: silence warning when CONFIG_SECURITYFS is not enabled
ima: Differentiate auditing policy rules from "audit" actions
ima: Do not audit if CONFIG_INTEGRITY_AUDIT is not set
ima: Use audit_log_format() rather than audit_log_string()
ima: Call audit_log_string() rather than logging it untrusted
